K frame lowering blocks

IMO, you're puttin the cart before the horse. You should make sure you need that crap first and then figure out how to go about it. A drop base air cleaner is a much easier option. Depending how the hood is made in that area, you may not even need lowering blocks. Did the original Hyper Pack cars have them? Ask @Hyper_pak what he did to his. Didn't his car have that manifold?
